| Notes | The Type 89 was initially designed as a light tank, but subsequent improvements added to the weight and the vehicle was classed as a medium. It bore some semblance to the British Vickers C and after various trials and modifications it was standardised as the main battle tank and used in battle in China and Manchuria. The 89A was armed with a short barrelled type 90 57mm gun and two machine guns which was adequate for the infantry support role but suffered from having a high silhouette. It was given the designation Type 89A Ko, when the improved model Otsu was introduced. |
